Mechanism of the effect of Fe/Ca oxide on coal pyrolysis to HCN

Meitan xuebao
Fe2O3 and CaO are the main metal oxides in coal, which have an effect on NOx precursor-HCN generation during coal pyrolysis. In order to reveal the mechanism of Fe2O3 and CaO on HCN generation during coal pyrolysis, this paper adopts pyrrole as a ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles

Advanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

N‐Doping Activated Presodiation Enhances Sodium‐Ion Provision in Hard Carbon Anodes

Advanced Science, EarlyView.
Introducing pyrrolic‐N sites enables efficient presodiation and stronger PF6− capture, thus pre ‐ forming a robust inorganic‐rich SEI layer in hard carbon anodes. ABSTRACT Hard carbon (HC) is considered the most promising anode material for commercial sodium‐ion batteries (SIBs), yet it still faces critical challenges such as low initial Coulombic ...

Tailoring Multifunctional Carbon Dots via Precursor Stoichiometry: Switching Between Solid‐State Fluorescence and Broadband Absorption Through Aggregation Control

Advanced Science, EarlyView.
Precursor stoichiometry programs the surface chemistry of carbon dots, directing their self‐assembly into distinct aggregation modes. Aldehyde‐enriched surfaces form ordered, hydrogen‐bonded assemblies that enable bright red solid‐state fluorescence, whereas amine‐rich surfaces promote compact π–π stacked aggregates with broadband visible‐light ...

Pyrrole and Fused Pyrrole Compounds with Bioactivity against Inflammatory Mediators [PDF]

Molecules, 2017
A new series of pyrrolopyridines and pyrrolopyridopyrimidines have been synthesized from aminocyanopyrroles. The synthesized compounds have been characterized by FTIR, 1H-NMR and mass spectroscopy. The final compounds have been screened for in vitro pro-inflammatory cytokine inhibitory and in vivo anti-inflammatory activity.
